If you have bi-wire cables and non-biwire speakers, just put both + wires together (and minus) on the single speaker terminal. Then run a jumper.
Your speakers were probably designed for two separate pairs of speaker cables, instead of an internal biwire pair.
The two sets of outputs on the amp are probably wired together inside the amp. There is no benefit connecting all 4 separately.
